This is a SBIR Phase I project to develop a novel non-intrusive surface temperature measurement technique for the in- situdetermination of both temperature and emissivity. The technique employs small local modulation of the temperature of the surface to be measured and detection of the modulated surface radiation. By modulating the surface radiation, extraneous radiation from other surrounding bodies is excluded, and the spectral shape of the modulated radiation is a function of surface temperature. The objective of the project is to demonstrate the technique at temperatures in the range of 1700 K. The approach will be primarily experimental and will involve the construction of a test system, and comparison of the results obtained from this technique with those of conventional techniques. The successful application of this device would be useful in monitoring industrial processes, boiler operation, diagnostics in gas turbines, jet engines, and rockets, and various control applications.

这是一个SBIR I期项目，旨在开发一种新型的非侵入性表面温度测量技术，用于对温度和发射率的固定化。 该技术采用了距离测量表面温度的小局部调节，并检测了调制的表面辐射。 通过调节表面辐射，排除了来自其他周围物体的外部辐射，并且调制辐射的光谱形状是表面温度的函数。 该项目的目的是证明在1700 K范围内的温度下的技术。该方法将主要是实验性的，并将涉及测试系统的构建，并比较从该技术获得的结果与传统技术的结果。 该设备的成功应用将有助于监视工业流程，锅炉操作，燃气轮机，喷气发动机和火箭的诊断以及各种控制应用。
